BACKGROUND

Numerous games involving beverages are known. Beer-Pong, also known as “Beirut,” is one such game and typically involves beer or other alcoholic beverages. Although numerous variations in the rules of the game exist, typically two teams of two or more people take turns throwing or bouncing balls into drinking cups. The game is played on a smooth, flat rectangular table or similar surface, typically one having a length between six to eight feet. Each team has a group of cups (typically 6 or more) centrally placed at opposite ends of the playing surface, said cups arranged in a close fitting triangular pattern (such as a 3-2-1 pattern) with the rims of the cups abutting one another. In this arrangement, each group of cups resembles an initial rack of balls in a game of pool. Each cup is filled, or partially filled, with a liquid beverage of choice, typically beer.

Play typically consists of each team taking turns trying to eliminate the other team's cups by directly throwing or bouncing a ball (such as a ping-pong ball or beer-pong ball) across the length of the playing surface and into one of the opposing team's cups. If a ball lands in a cup, that cup is taken out of play, and a member of the team whose cup was eliminated drinks the beverage contained within the cup. Play continues until the winning team eliminates all of the opposing team's cups. The losing team then drinks the contents of the winning team's remaining cups.

Although numerous games exist, including games involving beverages, there nevertheless remains a need in the art for new games, especially those with sufficient complexity that player participation and enjoyment are enhanced. Because games involving beverages are typically played in a variety of venues, a need also exists for such games that are readily portable.

Accordingly, in some embodiments provided is a game system, comprising: (i) at least one ball; and (ii) a first and at least one additional stackable tier. Alternatively, it may be advantageous for a game system to be packaged and sold as one or more stackable tiers and a plurality of receptacles. Accordingly, in some embodiments provided is a game system, comprising: (i) a plurality of receptacles adapted to hold a liquid; and (ii) a first and at least one additional stackable tier. Alternatively, it may be advantageous for a game system to be packaged and sold as one or more stackable tiers, a ball, and a plurality of receptacles. Accordingly, in some embodiments provided is a game system, comprising: (i) at least one ball; (ii) a plurality of receptacles adapted to hold a liquid and receive the at least one ball; and (iii) a first and at least one additional stackable tier. In the various embodiments, the game system may optionally comprise a carrying case adapted to receive and compactly store a disassembled game system.

The described embodiments will be better understood by reference to the figures, which are offered by way of illustration and which one of skill in the art will recognize are not meant to be limiting. Referring to FIG. 1, illustrated is a game system 1 comprising a first 2, second 3, and third 4 stackable tier, wherein said stackable tiers are arranged in a stack. Each stackable tier 2, 3, 4 comprises a body 5 and legs 6. Legs 6 may be of any suitable size and shape. As one illustrative example, cylinders having a diameter of 0.5 inch and height of 3.75 inches may be suitable for legs 6. Similarly, a stackable tier 2, 3, 4 may be supported by any suitable number of legs 6. As one illustrative example, four legs 6 may be suitable. One of skill will understand that stackable tiers lacking legs are also within the scope of the present application. Each body 5 comprises a substantially planar top 7 and plurality of receptacle apertures 8 defined therein, each receptacle aperture 8 adapted to receive a receptacle 9. The substantially planar top 7 may be molded into, permanently attached to, or removably attachable to the body 5. As shown, each receptacle aperture 9 is substantially circular in shape. However, one of skill will understand that a variety of shapes (or portions thereof) and sizes are within the scope of the present application. Similarly, a body 5 may be of any suitable size and shape, and may be the same for each, or different for each, stackable tier 2, 3, 4. As one illustrative example, a first stackable tier 2 may have a circular body 5 with a diameter of 15.5 inches and a height of 1.5 inch; a second stackable tier 3 may have a circular body 5 with a diameter of 14.2 inches and a height of 1.5 inch; and a third stackable tier 4 may have a circular body 5 with a diameter of 12.6 inches and a height of 1.5 inch. One of skill will understand, however, that such dimensions are non-limiting. For example, the first stackable tier 2 may be of smaller dimensions (and have fewer receptacle apertures 8) than the second tier 3, and the second tier 3 may be of smaller dimensions (and have fewer receptacle apertures 8) than the third tier 4. In some embodiments, a body 5 may also optionally comprise a plurality of tees 10 received therein, said tees 10 being one way of keeping score when the game system 1 is played. For example, when a player tosses or bounces a ball (not shown) into a receptacle 9, said player may take a tee 10 that is proximate to said receptacle 9.

Referring to FIGS. 2-5, illustrated are various views of the third stackable tier 4 of FIG. 1 without receptacles 9. As shown, the body 5 comprises a substantially planar top 7 and sides 11. One of skill will understand that the top 7 may also be non-planar and still be within the scope of the present application. The height (not labeled) of the body comprises the height of the substantially planar top 7 and the height of the sides 11. The height may vary according to the specific application and body design. For example, a body lacking legs may have a greater height than a body with legs. As another example, the height may be de minimis. As shown, the body is hollow between the substantially planar top 7 and the bottom 12. However, it is also contemplated that a body 5 may be solid between the substantially planar top 7 and bottom 12. As shown, the substantially planar top 7 comprises a plurality of optional tee apertures 13 defined therein, each located proximate to a receptacle aperture 8 and adapted to receive a tee 10. The stackable tier 4, as shown, comprises four legs 6, each removably attached to the body 5 with a bracket 14. One of skill in the art will appreciate that any suitable bracket or other apparatus may be used to secure legs 6 to the body 5. The bracket 14 shown secures to the body 5 with screws (not shown) and comprises a first recess 15 and a second recess 16, each being of suitable size and dimension to receive a portion of a leg 6. When all legs 6 are received in the first recess 15, the stackable tier 4 may be stacked as shown in FIG. 1. When all legs 6 are received in the second recess 16, the stackable tier 4 may be stored with the legs 6 securedly stored within the hollow portion of the body 5. One of skill in the art will also appreciate that the legs may be permanently secured to the body 5 or reversibly securable to the body 5. As shown, the third stackable tier 4 is adapted to receive four receptacles 9. However one of skill in the art will appreciate that because the tier 4 may be of variable size and shape and because the receptacles 9 may be of variable size and shape, the number of receptacles 9 that can be received within a third tier 4 be more or less.

Referring to FIG. 6, illustrated is a top view of the second stackable tier 3 of FIG. 1 without receptacles 9. As shown, the substantially planar top 7 comprises an optional secondary aperture defined therein. The secondary aperture 17 has a diameter that is less than that of a receptacle aperture 8. Optionally, in playing the game, if a ball (not shown) is tossed or bounced through the secondary aperture 8, at least one player must drink a beverage or perform some action. For example, the player that tossed or bounced the ball would be required to take a shot of an alcoholic beverage. As shown, the second stackable tier 3 is adapted to receive six receptacles 9. However one of skill in the art will appreciate that because the tier 3 may be of variable size and shape and because the receptacles 9 may be of variable size and shape, the number of receptacles 9 that can be received within a second tier 3 be more or less.

Referring to FIGS. 7-8, illustrated are top and bottom views of the first stackable tier 2 of FIG. 1, wherein FIG. 7 shows the tier 2 with receptacles 9 and FIG. 8 shows the tier 2 without receptacles 9. As shown, the first stackable tier 2 is adapted to receive 7 receptacles 9. However one of skill in the art will appreciate that because the tier 2 may be of variable size and shape and because the receptacles 9 may be of variable size and shape, the number of receptacles 9 that can be received within a first tier 2 be more or less.

Referring to FIGS. 9-10, illustrated are optional embodiments of the provided game system 1 in which the stackable tiers 2, 3, 4 may be adapted to disassemble and be compactly stored together. One possible storage configuration is shown. However, one of skill will understand that other configurations are also within the scope of the present application. The game system 1 may also be packaged and sold in such manner. Optionally, the game system 1 may comprise a carrying case 18 adapted to receive and store the disassembled stackable tiers 2, 3, 4. Thus, in some embodiments, the provided game system 1 is portable. In some embodiments, a carrying case 18 may also be adapted to receive and store one or more of a ball (not shown) and a plurality of receptacles 9 (not shown).
